COM-DRY series

Refrigerant+Adsorption dryer

General Details

COM-DRY dryers have been designed for continuous separation of water vapour from compressed air thus reducing dew point. Drying consist of two steps. Refrigerant dryer first eliminates large majority of water and reduces dew point down to PDP +3 °C. Further reduction of dew point ( down to PDP -70 °C ) is carried out by adsorption dryer. Operation of dryer is more simple compared to conventional heat regenerated adsorption dryer while average compressed air loses present only up to 4,6 %.

Techical Info



Operating presure 4 – 16 bar
Operating temperature 1,5 °C to 60 °C
Pressure dew points -40 °C ( -25, -70)


*If dryer is supplied without inlet filter compressed air class1 (ISO 8753-1) for solid particles and oil should be provided to the inlet of the dryer.
**Purge air consumption is related with inlet temperature to the adsorption dryer (outlet temperature from refrigerant dryer). Typically inlet temperature to adsorption dryer is 10 °C lower then inlet temperature to refrigerant dryer. In case inlet temperature to refrigerant dryer is lower than 35 °C demand for purge air increases.
